In any given year, 4 million tweens and teens are in the process of having their teeth straightened with braces or clear aligners. It's so common we tend to consider orthodontic treatment for young people as a rite of passage into adulthood.
But it doesn't necessarily have to be that way—it might be possible to stop or at least minimize a poor bite before it fully develops. That's the goal of interceptive orthodontics—treatments that head off or “intercept” a bite problem early.
The goal isn't necessarily to reposition misaligned teeth, but to correct a problem that can lead to misalignment. Here are some examples.
A narrow jaw. A narrowly developing jaw can crowd incoming teeth out of their normal positions. For the upper jaw, though, we can take advantage of a temporary separation in the bones in the roof of the mouth (palate) with a device called a palatal expander. Placed against the palate, the expander exerts outward pressure on the teeth and jaw to widen this separation. The body fills in the gap with bone to gradually widen the jaw.
Abnormal jaw alignment. It's possible for a jaw to develop abnormally during childhood so that it extends too far beyond the other. Using a hinged device called a Herbst appliance, it's possible to interrupt this abnormal growth pattern and influence the bones and muscles of the jaw to grow in a different way.
Missing primary teeth. An important role for a primary (baby) tooth is to hold a place for the future permanent tooth. But if the primary tooth is lost too soon, other teeth can drift into the space and crowd out the intended permanent tooth. To prevent this, we can insert a space maintainer: This simple looped metal device prevents teeth from drifting and preserves the space for the permanent tooth.
Although these and other interceptive treatments are effective, some like the palatal expander do their best work within a limited age frame. To take advantage of interceptive orthodontics in a timely manner, parents should seek a bite evaluation for their child from an orthodontist around age 6. The earlier we detect a growing bite problem, the greater your chances for successful intervention.

You can't correct a poor bite with braces or clear aligners overnight: Even the most cut-and-dried case can still require a few years to move teeth where they should be. It's a welcome relief, then, when you're finally done with braces or aligner trays.
That doesn't mean, however, that you're finished with orthodontic treatment. You now move into the next phase—protecting your new smile that took so much to gain. At least for a couple of more years you'll need to regularly wear an orthodontic retainer.
The name of this custom-made device explains its purpose: to keep or “retain” your teeth in their new, modified positions. This is necessary because the same mechanism that allows us to move teeth in the first place can work in reverse.
That mechanism centers around a tough but elastic tissue called the periodontal ligament. Although it primarily holds teeth in place, the ligament also allows for tiny, gradual tooth movement in response to mouth changes. Braces or aligner trays take advantage of this ability by exerting pressure on the teeth in the direction of intended movement. The periodontal ligament and nature do the rest.
But once we relieve the pressure when we remove the braces or aligners, a kind of “muscle memory” in the ligament can come into play, causing the teeth to move back to where they originally were. If we don't inhibit this reaction, all the time and effort put into orthodontic treatment can be lost.
Retainers, either the removable type or one fixed in place behind the teeth, gently “push” or “pull” against the teeth (depending on which type) just enough to halt any reversing movement. Initially, a patient will need to wear their retainer around the clock. After a while, wear time can be reduced to just a few hours a day, usually during sleep-time.
Most younger patients will only need to wear a retainer for a few years. Adults who undergo teeth-straightening later in life, however, may need to wear a retainer indefinitely. Even so, a few hours of wear every day is a small price to pay to protect your beautiful straightened smile.

While retainers are often viewed as a nuisance, they’re crucial to protect the gains made with bite correction. Without them, all of the progress achieved through braces or clear aligners could be lost.
Here’s why: The same elastic gum tissue called the periodontal ligament that holds teeth in place also allows them to move incrementally in response to changes in the mouth. That’s why we can move teeth with braces or aligners, which put pressure on the teeth toward a desired direction of movement while the periodontal ligament does the rest.
But the mechanics can also work in reverse: With pressure relieved when the braces are removed, the teeth could revert to their original positions through a kind of “muscle memory.” The light pressure provided by a retainer is enough to keep or “retain” teeth in their new positions.
The best known retainer is a removable appliance. Initially, a patient wears it continuously and only takes it out during oral hygiene. Wear duration may later be reduced to night time only and eventually not at all, depending on a patient’s individual needs.
While effective, removable retainers do have some downsides. Like braces, they’re visible to others. And because they’re removable, they’re frequently misplaced or lost, leading to the added expense of a new one.
An alternative is a bonded retainer, a thin piece of wire attached to the back of the newly moved teeth to keep them in place. Because it’s behind the teeth it’s not visible—and there’s no misplacing it because only a dentist can take it out.
A bonded retainer is a good option, especially if a patient is immature and not as diligent about wearing or keeping up with their appliance. But it can make flossing difficult to perform, and if they’re removed or broken prematurely, the teeth could revert to their former positions.
If you decide to go with a bonded retainer, be sure you get some tips from your dental hygienist on how to floss with it. And if you decide later to have it removed early, be sure to replace it with a removable retainer. Either of these two options can help you keep your new and improved smile.

Approximately 4 million tweens and teens are currently undergoing orthodontic treatment for a poor bite (malocclusion) that can cost their families thousands of dollars in braces or clear aligners. But treatment doesn't always have to follow this track: Found early, many malocclusions can be corrected or minimized before they fully develop.
Known as interceptive orthodontics, this particular approach to bite correction often begins as early as 6-10 years of age. Rather than move existing teeth, interceptive orthodontics focuses instead on redirecting jaw growth and intervening in other situations that can cause malocclusions.
For example, a child's upper jaw may not be growing wide enough to accommodate all incoming permanent teeth, crowding later arrivals out of their proper positions. But taking advantage of a gap during early childhood that runs through the center of the palate (roof of the mouth), orthodontists can increase jaw width with a device called a palatal expander.
The expander fits up against the palate with “legs” that extend and make contact with the inside of the teeth. With gradually applied pressure, the expander widens the central gap and the body naturally fills it with new bone cells. The bone accumulation causes the jaws to widen and create more room for incoming teeth.
Another way a malocclusion can develop involves the primary or “baby” teeth. As one of their purposes, primary teeth serve as placeholders for the future permanent teeth forming in the gums. But if they're lost prematurely, adjacent teeth can drift into the vacant space and crowd out incoming teeth.
Dentists prevent this with a space maintainer, a thin metal loop attached to the adjoining teeth that puts pressure on them to prevent them from entering the space. This spacer is removed when the permanent tooth is ready to erupt.
These and other interceptive methods are often effective in minimizing the formation of malocclusions. But it's often best to use them early: Palatal expansion, for example, is best undertaken before the central gap fuses in early puberty, and space maintainers before the permanent tooth erupts.
That's why we recommend that children undergo an orthodontic evaluation around age 6 to assess their early bite development. If a malocclusion looks likely, early intervention could prevent it and reduce future treatment costs.

The monarchs of the world experience the same health issues as their subjects—but they often tend to be hush-hush about it. Recently, though, the normally reticent Queen Elizabeth II let some young dental patients in on a lesser known fact about Her Majesty's teeth.
While touring a new dental hospital, the queen told some children being fitted for braces that she too “had wires” once upon a time. She also said, “I think it's worth it in the end.”
The queen isn't the only member of the House of Windsor to need help with a poor bite. Both Princes William and Harry have worn braces, as have other members of the royal family. A propensity for overbites, underbites and other malocclusions (poor bites) can indeed pass down through families, whether of noble or common lineage.
Fortunately, there are many ways to correct congenital malocclusions, depending on their type and severity. Here are 3 of them.
Braces and clear aligners. Braces are the tried and true way to straighten misaligned teeth, while the clear aligner method—removable plastic mouth trays—is the relative “new kid on the block.” Braces are indeed effective for a wide range of malocclusions, but their wires and brackets make it difficult to brush and floss, and they're not particularly attractive. Clear aligners solve both of these issues, though they may not handle more complex malocclusions as well as braces.
Palatal expanders. When the upper jaw develops too narrowly, a malocclusion may result from teeth crowding into too small a space. But before the upper jaw bones fuse together in late childhood, orthodontists can fit a device called a palatal expander inside the upper teeth, which exerts gentle outward pressure on the teeth. This encourages more bone growth in the center to widen the jaw and help prevent a difficult malocclusion from forming.
Specialized braces for impacted teeth. An impacted tooth, which remains partially or completely hidden in the gums, can impede dental health, function and appearance. But we may be able to coax some impacted teeth like the front canines into full eruption. This requires a special orthodontic technique in which a bracket is surgically attached to the impacted tooth's crown. A chain connected to the bracket is then looped over other orthodontic hardware to gradually pull the tooth down where it should be.
Although some techniques like palatal expanders are best undertaken in early dental development, people of any age and reasonably good health can have a problem bite corrected with other methods. If you are among those who benefit from orthodontics, you'll have something in common with the Sovereign of the British Isles: a healthy, attractive and straighter smile.
